FORGE BURNER AND IGNITION MEANS Filed April 16, 1947 INVENT'QR /Q- raw 14/5/4516 Patente pr. 25, 1950 Ii STATES PATENT OFFICE 2 Claims.

This invention relates to improvements in fuel oil or distillate burner heads, and more particularly to a novel burner head including a quick igniting means.

An object of the invention is to provide a burner head having a spark plug igniter and integral switch means for quick operation thereof.

Other and further objects of the invention will appear as the description proceeds, reference being had to the accompanying drawing, in which:

Fig. 1 is a side view partly in section and partly in elevation of a forge burner embodying my invention.

Fig. 2 is a front view in elevation of the device.

Fig. 8 is a plan diagrammatic view of the device.

Fig. 4 is a plan view of the forge burner head.

Referring more particularly to the drawing, numeral it represents a precast refractory tuyre nozzle, having the central opening at i I in outline similar to that of a figure 8 A mixing chamber is provided within the cylindrical wall I2 having the circular air inlet openings spaced therein as at l3 and HE. A conventional spark plug I5 is mounted in a plate I6 which is hinged at the bottom thereof on the rod ll. The plate It has rigidly affixed thereto and extending laterally thereon the lever l8 which with its end I 9 is adapted to impinge against the push button of the contact switch 2| to close an electrical circuit 22 for the purpose of energizing the spark plug l5. The wall 2 has an integral bottom 23 provided with air inlet apertures as at 24 circularly arranged therein. A two piece Venturi type atomizer 25 is engaged in a threaded aperture at 26 of the bottom 23, and the element 25 is vertically bored and threaded in the lower portion of said bore to receive the compressed air inlet nozzle 21, engaging the air pipe 28. The element 25 has a lateral horizontal bore at 29 to receive the oil inlet pipe 30.

In use, the plate It will normally be vertically aligned with the wall l2 against the stop 3|. When it is desired to use the burner head, the air and oil will be turned on, and the air will atomize and force said oil upwardly into the chamber formed by the wall l2 at bottom 23. The plate It may then be pushed inwardly of said wall I2 until the lever I8 impinges with its end i9 against the push button 20 of the contact switch 2 l. The electrode 32 of the spark plug IE will then be energized to provide a spark for ignition of the atomized mixture causing the oil flame to jet through the opening at l i. The opening may be formed in either circular or oval shape, but in the form as shown, I have found a very hot flame to result.

It will be understood that the device is capable of many modifications in structure and design, without departing from the spirit of the invention, within the scope of the appended claims.

Having thus described my invention, what I desire to secure by Letters Patent of the United States, is:

1. A forge burner including a refractory nozzle, a cylindrical wall subjoined thereto, a bottom wall on the cylindrical wall, a fuel atomizing nozzle coaxial of said cylindrical wall and carried 'by said bottom wall, adapted to atomize fuel upwardly through said cylinder into said refractory nozzle, an inwardly moveable door in said cylinder wall, a spark plug carried by and having electrodes extending inwardly of said door, a switch carried by said cylindrical wall for energizing said spark plug, and means on said door to operate said W switch when the door is manually tilted inwardly to move the spark plug into the path of said atomized fuel for ignition thereof.

2. A forge burner including a refractory nozzle, a cylindrical wall subl'oined thereto, a bottom wall on the cylindrical wall, a fuel atomizing nozzle coaxial of said cylindrical wall and carried by said bottom wall, adapted to atomize fuel upwardly through said cylinder into said refractory nozzle, a door hinged at the lower end thereof and moveable inwardly of said cylindrical wall, a spark plug carried by and having electrodes extending inwardly of said door, a switch carried by said cylindrical wall for energizing said spark plug, and means on said door to operate said switch when the door is manually tilted inwardly to move the spark plug into the path of said atomized fuel for ignition thereof.
